MIC4930Hyper Speed ControlВ® 3A Buck RegulatorFeatures General Description The MIC4930 is a high-efficiency, 3A synchronousbuck regulator with ultra-fast transient responseperfectly suited for supplying processor core and I/Ovoltages from a 5V or 3.3V bus. The MIC4930 providesa switching frequency up to 3.3 MHz while achievingpeak efficiencies up to 95%. An additional benefit ofhigh-frequency operation is very low output ripplevoltage throughout the entire load range with the use ofa small output capacitor. The MIC4930 is designed foruse with a very small inductor, down to 1 ОјH, and anoutput ceramic capacitor as small as 10 ОјF without theneed for external ripple injection. A wide range ofoutput capacitor types and values can also beaccommodated.
